Ascension Island is an isolated volcanic island in the equatorial waters of the South Atlantic Ocean, around 1,600 km from the coast of Africa and 2,250 km from the coast of Brazil, which is roughly midway between the horn of South America and Africa. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 1,300 km to the southeast. The territory also includes the sparsely populated Tristan da Cunha archipelago, some 3,730 km to the south, about halfway to the Antarctic Circle.

The island is named after the day of its recorded discovery, Ascension Day, and is located at 7°56′S 14°22′WCoordinates: 7°56′S 14°22′W, about as far south of the equator as tropical Venezuela is to its north. It played a role as an important safe haven and coaling station to mariners and for commercial airliners during the days of international air travel by flying boats. During World War II it was an important naval and air station, especially providing antisubmarine warfare bases in the Battle of the Atlantic. Ascension Island was garrisoned by the British Admiralty from 22 October 1815 to 1922.

The island is the location of RAF Ascension Island, which is a Royal Air Force station with a United States Air Force presence, a European Space Agency rocket tracking station, an Anglo-American signals intelligence facility and the BBC World Service Atlantic Relay Station. The island was used extensively by the British military during the Falklands War. Ascension Island hosts one of five ground antennas (others are on Kwajalein Island, Diego Garcia, Colorado Springs and Hawaii) that assist in the operation of the Global Positioning System (GPS) navigational system. The National Aeronautics and Space Administration and the United States Air Force operate a telescope on Ascension Island for tracking orbital debris, which are potentially hazardous to operating spacecraft and astronauts, at a facility called the John Africano NASA/AFRL Orbital Debris Observatory.,,,https://en.wikipedia.org/wiki/Ascension_Island

Volcano types: Stratovolcano Cinder cones Lava domes Summit Elev: 858 mLatitude: 7.95°SLongitude: 14.37°WAscensión Island, located just west of the Mid-Atlantic Ridge, was discovered on Ascensión Day, 1501, by the Portuguese navigator Joao da Nova. Ascensión is the broad emergent summit of a massive stratovolcano that rises 3000 m above the sea floor. The isolated island, 1130 km from the nearest land, is dotted with more than 100 youthful parasitic cones and lava domes, many aligned along two fissures. Basaltic rocks dominate on the 858-m-high island, although trachytic lava domes are also present, mostly on the eastern side. Although no eruptive activity has occurred since its discovery during the 16th century, many volcanic features on Ascensión have a very youthful appearance. Two of the youngest lava flows were erupted from flank vents and reached the sea on the northern and southern coasts.
